Preheat your oven to 190c/170c fan oven and line two 12 hole muffin tins with muffin cases (if you only have one muffin tray you can bake in batches). This recipe makes 15 muffins.
Into a bowl weigh out and add your flour, sugar, bicarb and baking powder then mix them together.
In another bowl add your bananas and mash them until smooth. Add eggs,oil and milk and whisk it all together.
Tip the dry ingredients into the wet and mix well until combined.
Divide the mixture between the cases and bake in the oven for 20-25 minutes. The muffins are cooked when a skewer inserted in the center of one comes out clean. Leave to cool and enjoy!
